Meanwhile, since the end cover plate shields the opening of the water guiding gutter 8, and also since the manual valve 21 is not yet opened, the water in the water guiding gutter 8 is prevented from entering the communication well 6 without being filtered.
And, after the filter layer 11 rises above the well head, the clamp on the water conduit 20 can be unfastened, and then detached from the connecting rod 12, and then sleeved on the input pipe 23 of the water pump 22 and fixed by the clamp, and the manual valve 21 is opened. At this time, the water in the water guiding ditch 8 is pumped out to the water outlet pipe 24 by the water pump 22, and the water can be used for flushing and cleaning the filtering layer 11. For cleaning, the filter layer 11 can also be rotated to be detached from the connecting rod 12. During cleaning of the filter layer 11, if the amount in the water guiding gutter 8 is insufficient, more water is introduced into the water guiding gutter 8 by opening the control valve at the connection of the ambient water source and the annular water collecting gutter 7.
